On the sand issue, I have a question, if you all don't mind. My tank is probably still cycling (established tank that recently moved to my house). It has an ug filter that I am using in conjunction with an HOB aquaclear 150. The ug is run by a 301 power head.
Can i remove all of my substrate and put sponges down under the ug filter (for added bio filtration) and then cover it with sand? Would you recommend taking the fish out? (I don't have another aquarium at the present). So I was thinking of leaving them in and doing a big water change again to take care of the nasty stuff kicked up in the process.
Lastly, what kinda sand (just regular old sand from teh hardware store)?
